inviability

Being hybrids, Savannahs typically exhibit some characteristics of hybrid inviability.

The knockout of this gene in E. coli leads to cell inviability.

Mutations crept in, sometimes producing improvements, more often resulting in inviability.

Hybrid sterility and inviability increase reproductive isolation, which leads to speciation.

Factors which prevent mating being successful, such as genetic incompatibility, hybrid inviability or sterility.

Hybrid inviability: Hybrid embryo forms, but is not viable.

Freeman was selected due to its inviability and large amount of empty space which could be used to store these aircraft and perform evaluation flights.

Hybrid inviability is a post-zygotic barrier, which reduces a hybrid's capacity to mature into a healthy, fit adult.

Thus, hybrid inviability acts as an isolating mechanism, limiting hybridization and allowing for the differentiation of species.

These different placenta types possess divergent immunological systems, and consequently, they cause varying degrees of hybrid inviability.

The Immunological Hypothesis proposes that the divergence of certain protein structures associated with mother and child causes hybrid inviability.

The Regulatory Hypotheses specifically attributes hybrid inviability in mammals, birds, and frogs to differences in gene regulation.

The barrier of hybrid inviability occurs after mating species overcome pre-zygotic barriers (behavioral, mechanical, etc.) to produce a zygote.

Wilson et al. (1974) proposes two hypotheses to explain the relatively faster evolution of hybrid inviability in mammals: the Regulatory and the Immunological Hypotheses.

The Regulatory Hypothesis accounts for two characteristics of mammals, and explains the general formation of hybrid inviability in mammals, birds, and frogs.

Another member of the war cabinet, a member of the plague axis, warns her that the paranoia of the Empire is leading them all into genetic inviability.

In the 1970s, Allan C. Wilson and his colleagues first investigated the evolution of hybrid inviability in tetrapods, specifically mammals, birds, and frogs.

Due the inviability of such a manner of death, Governor James Devlin re-writes the death penalty laws, allowing only lethal injection and electric chair as possibilities.

Currently, the most popular explanation for Haldane's rule is the composite hypothesis, which divides Haldane's rule into multiple subdivisions, including sterility, inviability, male heterogamety, and female heterogamety.

Orr is an evolutionary geneticist whose research focuses on the genetics of speciation and the genetics of adaptation, in particular on the genetic basis of hybrid sterility and inviability.

And yet, the same science and the same technology that contends of the inviability of the natural laws, the same time is able to set it, one law against it, another itself, and he can do what he wants.

In contrast, Elliot and Crespi (2006) documents the effects of placental immunology on hybrid inviability, showing that mammals with hemochorial placentas more readily hybridize than mammals with epitheliochorial or endotheliochorial placentas.

It proposes that hybrid inviability evolved faster in mammalian taxa because mammals have accumulated significantly more changes in regulatory systems than birds or frogs, and it suggests that organisms with distinctly different systems of gene regulation may not produce viable hybrids.

The stadium plan encountered difficulties however after the Debt Review Committee of Salt Lake County voted against the stadium proposal 4-0 on January 26, 2007 citing what they saw as Real Salt Lake's financial inviability as the reasoning behind the lack of support.
